Abstract: Background: The species Bidens pilosa, Euphorbia heterophylla, and Amaranthus hybridus have shown high interference in soybean cultivation, especially due to biotypes resistant to various herbicides. Objective: This study aimed to analyze the effectiveness of soil cover associated with pre-emergence herbicides in managing these species Methods: Separate experiments were conducted for each weed species in a completely randomized design with a 4 × 4 factorial scheme and three replications. The evaluated factors were chemical management (diclosulam, flumioxazin, sulfentrazone, and an […]

Abstract: Background: Vigna bean species have garnered increasing global interest due to their nutritional value and adaptability to unfavorable environmental conditions. Their expansion into Brazil’s Cerrado region, however, necessitates reliable herbicide strategies for effective weed suppression under high weed pressure, particularly from Commelina benghalensis. Objective: This study assessed the selectivity of commonly used herbicides and the potential interference of C. benghalensis in different Vigna cultivars. Methods: Two greenhouse experiments were conducted in 2022 and 2023 using cultivars of V. unguiculata […]

Abstract: Farmers have reported difficulty in controlling Ambrosia sp., observing uncontrolled plants in soybean fields even after post-emergence glyphosate application. The aim of this study was to evaluate the response of Ambrosia sp.to different rates of the herbicide glyphosate. The experiment was conducted in duplicate in a greenhouse at the Federal University of Santa Catarina, Curitibanos campus, between September and December 2022, using a completely randomized design with four replications. The treatments consisted of the application of nine increasing rates […]
